Cross-cut verification matrix for ADR-0032 Phase 2 is now fully populated with concrete test references — every row green. Filling the matrix surfaced three real gaps that this commit closes. 1. Advanced-mode syntax highlighting (ADR-0030 §8 matrix row). The `ui.rs` Advanced branch routed through `plain_input_spans`, bypassing the highlight walker entirely. In production SQL keywords past the entry word rendered as plain identifiers. Fix: mode-aware variants of `highlight_runs`, `render_input_runs`, `lex_to_runs`, and `input_diagnostics`; the Advanced render path now uses the highlighted form with `Mode::Advanced`. `plain_input_spans` removed (unused). 2. Engine.* key wiring (ADR-0032 §11.4 / §13 matrix rows + handoff §3.3 follow-up). The four Phase-2 engine.* catalog entries were authored in 2d but never reached: `translate_generic` discarded the engine message and returned a vague catalog entry. Fix: pattern-match the engine message text for the four Phase-2 categories (aggregate misuse, group-by required, compound arity mismatch fallback, scalar-subquery cardinality) inside `translate_generic`, routing each to its engine-neutral catalog entry. 3. Matrix-coverage tests. Thirteen new tests covering the rows that had no explicit coverage: - 3 SQL keyword/operator/CASE highlight tests - 4 engine.* engine-message tests - 3 sql_expr column-completion tests (WHERE, HAVING) - 3 predicate-warning slot tests (CASE, ORDER BY, projection) - 1 all-10-playground-types recovery test (tests/sql_select.rs) Plan document (docs/plans/20260520-adr-0032-phase-2.md) updated: every (TBD) row in the cross-cut matrix replaced with a concrete test file::function reference and a green status marker. Test totals: 1428 → 1441 passing (+13 new). Clippy clean.
